Abstract:
|
A smooth simultaneous confidence band (SCB) is proposed for a local measure of variance explained by regression, termed correlation curve in Doksum et al (1994), based on local quadratic estimation. The proposed estimator of correlation curve is oracally efficient in the sense that it is as efficient as an infeasible correlation estimator with the variance function known. Simulated and real-data examples are provided to illustrate the usefulness of the proposed oracle SCB.
